You can get 40 stations out of an Adit-600 using MGCP as long as you don't need to use G.729.  I 
beleive it only supports 24 g.279 calls at one time.  

Two of these mount side-by-side in a rack using two rack-units, giving you 80 ports in the space 
many other devices will give you 48 ports.

Sadly, It seems that "rack and stack" is the cheapest way to go.
